Design of Multi-Domain Joint Coding Scheme Based on Circular Mapping

Abstract

With the rapid development of wireless communication technology and the increasing demand for communication quality in various fields, spread spectrum communication (SSC) and multiple input multiple output (MIMO) technology have become crucial research directions in the field of military communication, and space-time block coding (STBC) is an indispensable key technology in MIMO systems. This paper combined the excellent instrument interaction ability of LABVIEW and the data processing ability of MATLAB to build a direct sequence spread spectrum-space time block coding (DSSS-STBC) model based on circular mapping (CM) spread spectrum code, aiming at realizing multi-domain joint transmission of information in space, time, and power domains. The results demonstrated that the joint simulation platform of LABVIEW and MATLAB/Simulink successfully confirmed the superior spread spectrum performance of chaotic spreading codes based on circular mapping compared to traditional spreading codes. In addition, the multi-domain joint coding combining DSSS and STBC significantly enhanced the reliability and interference resistance of the communication system.
